Place brie on parchment-lined rimmed baking pan; drizzle with honey. Transfer to oven and bake 10 to 12 minutes or until inside of cheese is softened, but outside remains intact.
Transfer brie to serving platter; top with pomegranate arils, pistachios and mushrooms. Serve immediately with crackers or bread.
Notes
Home Chef Tip: To get deeply golden brown sautéed mushrooms, use the largest skillet you can get your hands on. A crowded skillet means the mushrooms will steam instead of getting nice and brown. Also - hold off on the salt until the end. Salt too early, and you'll draw the moisture out of the mushrooms, which again means steaming, not browning.
